Study Notes
Authentication Factors
- An example of a possession factor for authentication is a smartphone app that receives a one-time password (OTP) or a smart card.
- Multifactor authentication is considered strong because it requires multiple forms of verification, making it more difficult for attackers to gain unauthorized access.
- A fingerprint is a type of inherent factor in authentication, also known as a biometric factor, which uses unique physical characteristics to verify an individual's identity.
- Using a single factor for authentication is less reliable because it can be compromised by a single vulnerability, such as a weak password or a stolen token, allowing unauthorized access.
